Seventeenth, in the peculiar mechanism for throwing the clutches rinto action for reversing the motion of the carriage, as hereafter described. y

In the drawings, the parts marked A indicate the main frame of the machine, and B, the driving-shaft, upon which are arranged the tight pulley C, loose pnllev 1),'and ratchct-pulley E, together with the drivingpulley F, all arranged in the usual manner.

Upon the end of the driving-shaft B is a double pulley, G, from one part of which a belt, a, extends upward to the pulley b, on shaft c, which operates the twist-wheel (l, and mechanism connected therewith, which mechanism, heilig larranged inthe ordinary manner. will need no further explanation.

From the ot-ltcr part of the double pulleyfG, a belt extendsto the pulley c, ou the end of a shaft, f, by means of which the mechanism of the mule-head is operated. The shaft f is supported andA turns in bearings at the upper part of the head-frame H,\and it is provided with a coiie-iiulley, I, from which a belt, (1, extends to a corresponding cone-pulley, J, ou a central shaft, Tt, which hitter is also arranged in bearings on the trame 1-1, iu a similar manner to shaft j`,and which has, near its central part, a pinion, t', that meshes into and operates the gear K, upon the main shaft L, as fully indicatedin the drawings.

The main shaft L is supported and turns-in bearings ou the frame H, and upon it are arranged the draughtscrolls M and N, one of which (M) diaws the carriage out, and the othcr(N) draws it in when in operation. The scrolls M and N are made to turn loosely on the main shaft L, but are connected thereto for operation by means of the clutches 0 and P, one of which (0) is a friction-clutch, and operates t-lie scroll M ,.while the other (P) is a toothed clutch, and operates the scroll N. The clutch P is thrown into gear by an upright lever', lc, and the""clutch O by a similar upright lever, 1, both of which are pivoted, at their lower ends, to the bottom part of the frame H, with their upper ends working between pins m fm, that project from the back of the slide-bar Q, all of which is fully shown in the drawings.

The scroll M is connected to the carriage by means of two cordska and p, one (n) being the draught-cord, which passes around a pulley, q, at the front of the machine, and has its end fastened to the lower end of a downward projecting stud, r, at the under side of the carriage-frame It, while the other (.p) is attached to the rear side of the `carriag. ,fefrarne, and acts as a steadier, to prevent a too rapid or unsteady motion when the carriage is moving ont.

The beltgis kept taut by a pair of pressure-pulleys, S, attached to the arms of the slide T, and held a-gainst the belt g by the pressure of a weight, t, at the end of the stud u, which stud projects backward from the slide T, as shown in the drawings.

The slide T is arranged to move on a rod, V, placed A diagonally across the head-frame H, and it is run back and forth by means of a cord, w, fastened at its central part to the stud u, and at one of its ends to the regulating-arm W, while the other end passes over a pulley, ai, and has attached to it a weight, X, by means of which the slide T is drawn toward the upper end of the rod V, together with the pressure-pulleys S and bandl g. The cord w is fastened to the arm` W by an eye-bolt, y, which is inserted in one of the holes z, at the upper end of the arm W, as shown in iig. 2 of the drawings.

The`lower end of the regulating-arm W is pivoted l upon a stud, s, which projects backward from the standard A', and it has arranged near its central part. a roll, r, that runs on the edge of 'the guide-cam B', by means of which the regulating-arm W' is operated. The guide-cam is turned, when the car'riage is running out, by means of a cord, al, one end of which .is attached to a stud, b1, beneath the carriage-frame R, the other end being coiled around and fastened to a dan ged wheel, c, that is` hung and turns on thesame stud Y that supports the cam B'. Y

Attached to the flanged wheel c1 is a drum, dl, having secured to its circumference one end of a weightcord, el, which passes over a pulley, f, at the` upper -part of the frame A, and is furnished at its end with a weight, g1, as indicated in the drawings. In the interior ofthe drum d1 is arranged a dog, 1, made as shown in fig. 8 of the drawings, and furnished witha spring, 2, to press the hook part of the dog 1 outward against the shell of the drum d1, and thereby cause it to engage with a pin, 3, that projects into the interior of the drum d from the side of the friction-wheel h, which latter' is operated thereby, together with the guide-cam B', which is secured tothe outer side of the friction-wheel h, by a screw or bolt, A frictionband, k', is arranged around the wheel h1, to prevent it from turning except when forced around by the dog 1. The tension of the friction-band k may be varied by means of a nut ou the tension-bolt l', which bolt is arranged to pass through the stud s,

When the carriage is run out, theA cord al is unwound from the danged wheel c1, thereby causing said wheel, together with the drum. d', to revolve in the direction indicated by the arrow, tig. 8.

After the carriage has run out for a certain distance, the hook of dog 1 engages the pin 3, and while the carriage is travelling the remainder of the distance out, the guide-ca rn B' is caused to make just one coniplete revolution, thereby swinging the arm W outward and back to its original position, which operation moves the belt q along the cone-pulleys I and J,

vwhich increases and diminishes the speed of the latter',

and also the speed of the main shaft L and draughtscroll M, thereby moving the carriagewith a greater velocity for a portion of thefdistance out.

The weight-cord e iswound upon the drum d1 as the carriage is run out, thereby raising the weight g, and as the carriage is run in, the weight g1 descends and turns the drum tlL and flanged wheel c1 back to their former position, winding the cord al upon the flanged wheel c1, while the guide-earn B- remains stationary, it being held by the friction-band lo' on the wheel h1.

During the backward motion of the drum ll, the pin 3 passes under the point of the dog 1, (which is bevelled oi, as shown in fig. 8,) thereby raising it sufficiently to allow of the pin 3 passing freely beneath it without being acted on, while the drum Z1 is moving backward.

It will be observed, that with this mechanism the motion of the carriage can be perfectly controlled, as a greater. 0r lesser increase of speed can be obtained by simply changing the eye-bolt y to different holes, 2, in the arm W, thereb increasing or diminishing the leverage, and varying the distance to which the band g is drawn along the cone-pulleys I and J, While the maximum velocity may be obtained when the ca-rriage is at any particular part ofthe stretch, by making the guide-earn B' of such form that it will swing 1 out the arm 1V, at the time the carriage passes the given point. Thus it will be seen that the action of the carriage may be regulated so that the mule will spin any quality or kind of wool withequal facility.

At the side ot' the head-frame H is arranged a perpendicularA slide, C', which works up and down in the bearings 6, and is provided with a spiral spring, 4, by which it is drawn upward against the stop-pin O', and also with notches n', into which a latch-spring, m', catches, to hold the slide C' in different positions during its operation.

At the upper end of the slide O' is aninclined flange, 5, which operates the slide-bar Q, andlevers lc and ll, which throw the clutches of the draught-scrolls in and out. 1

A ratchet-bar, D'. is pivoted, at 11', to the side of the perpendicular slide C', by means of which the latter is moved down, said ratchet D being operated by a pawl-rod, F', from a crank-plate, G', fastened on the end of the shaft j'.

The ratchet-bar D' is pressed forward by a flat spring, q', a lip being formed at the upper end ofthe ratchetbar, which strikes against a pin, r', projecting from the side of the slide G,"thereby preventing the ratchetbar D'rfrorn being thrown too far forward.

The pawl-rod F' is pressed forward by a [lat spring, H', that rests on a pin, s', projecting from the side of the rod I1", at its lower' end, as fully indicated -in the drawings. y

The ratchet-bar D is vbevelled off at its front edge, and a rod, I', ext-ending from the shipper-har' J', is arranged through au eye, 7, on the front ot" frame H, so that when the shipper-bar J is moved, the end of rod I', coming in contact with the bevelled edge of the ratchet-bar D', swings back the latter, causing it to engage with the pawl-.rod F', whereby it is moved downward, carrying the slide C', and the partsconnected therewith. f

A lever, K', pivoted at t on the frame H, is valso arranged to press back the ratchet-bar D.

To the lower end of lever Kl is secured the end of a rod, L', which extends to the front of the machine, where it is supported by the projection n.

The rod L' has a finger, M', attached to it, against which the stud r strikes as the carriage runs out, and thereby draws forward the lowe'r end of the lever' K', and swings back the upper end thereof, in which is arranged a pin, v', that strikes the upper' end of the ratchet-bar D', and pr'esses it back, when it will be moved down "by the pawl-rod F for a distance equal to one notch of the ratchet, thus carrying the end ot' the ratcl1ctbar D below the pin 1:', when it is again pressed forward by the spring q. i

. rlhe rod J i' is pressed back, when the carriage is rnn in, by a coiled wire spring, w', one end ot' which rests against the projection u', and the other against the hub ot' the finger M', as indicated in tig. (i.

The finger M may be-adjusted on the rod L by means of the set-screw X. Y

The carriage-frame R is mounted upon grooved travelling-wheels U', in the usual manner, which run on the track-ways N', at the sides of the machine.

At the under side of the carriage-frame R, and supported by the hangers O', is the winding-shaft P', t'urnished, at its lett-hand end, with a pulley, (Q, and driven by abelt, R', from the pulley F on the drivingshaft B, which belt E also drives the cylinder T', and the compensating mechanism.

. Uponthe winding-shaft P is arranged a frictionclutch, V', to the `inner piece of whiclris attached the winding-drum W.

The winding-drum \V' is operated as the carriage is moved in or out, by the 'cords 8 and Q, one end of each heilig secured to the drum W", while the oppo` site end ot' the cord 8 is fastened to a pin, 10, projecting up from one of the bearings 11,'which support the worm-shalt 12 and the end ot' cord 9, heilig fastened to the upper end of the spring standard 13.

'lhc iiiction-clutch V is thrown into and out of gear by an arm, 14, secured to and proiect-ing down from the vcross-shaft 15, which shaft is supported transversely to and somewhat above the winding-shaft P' by the hangers 16, beneath the frame l of the carringe.

The spindles a? aremounted upon the i'rame R- of the carriage, and are operated, by bands b2, from the cylinder T', in the ordinary manner. The miler-rods c2 and (l2 are supported by standards e?, at `the iront of the frame It of the carriage, and

' the fallers fl andylarc held in an elevated position by means ot` spiral wire springs h", all ot' whichare fully indicated in the drawings.

l o the rod c2 ot' the under 'allcr f2 is secured a curved arm,.19, the end'ot' which is connected by a rod, 20, to the end of a rcgulating-spring, 2l, fastened to the forward end oi' the cross-shaft 15.

The rod d2 of the -upper taller g2 is provided with a segment, 22, by means ot' which it is operated.

rlhe segment 22 is `ioincd, by a cord or chain,'23, to the upper extremity of a perpendicular bar, 24, that moves up aud-down in bearings 25, on an upright standard, 26, atthe front side. oi the carriage, as shown in the drawings. f

Underneath the frame 1t ol thc carriage, and arranged to more back and forth, in lbearings 2T, on the right-hand hanger O', is a backing-oit' slide, 2S, for operating the upper i'aller 1/2, and for putting into operation the mechanism which backs oli' thc spindles a2, preparatory to winding up the yarn.

The backing-oit' slide 2S is provided with a downward-projecting arm, 2,5), near its rear end, which is connected by a cord, 30, to `the draught-scroll N, and

also by a cord ory chain, 31, to the periphery ot' the backing-oit clutch 32.

The iront end of thek slide 28 made with a perpendicular slotted head, 33, and it also has, near its central part, a switch, 34, for operating the lever 35 oi the backing-oit clutch. Y

The switch 34 is made as indicated by dotted lines, fig. (i, so that when the backingoff slide moves forward, the top of' the level' 35 passes to the left of the langc of the' switch, and when the slide 28 is moved back, the top of' lever o5 passes to the right ot' the flange of the switch, thereby1 throwing the backing-oft clutch into action.

The slide 28 is connected, by means of a rod, 36,4

tcd head 33, and the latter in the slotted projection 42, at thc lower ii'ont part of the right-hand hanger O. The stud-bolt 41 project-s through the slotted projection 42 snfiiciently far to take a. bearing upon the ccp-builder rail 43, while the stud-bolt 40 projects through the shackle-bar 39 sufficiently far to receive the curved shoulder in the lower end ot' the swinging arm 44. (Sec dotted lines, tig. 3.)

' The swinging arm 44 is hinged to the perpendicular bar 24, as shown inthe same figure.

The cop-builder rail is to be made adjustable, and operated by mechanism in the ordinary manner for building or forming the cops in the common way.

A latch-dog, 45, made in the form oi' a bell-crank, `is pivo'ted, at ,46, to the righthand hanger O', the horizontal arm of which is provided with a notch at the under s ide of its front end, to catch upon an adjustable catch-piece, 4T, which is secured to the bedframe 48. l v AY.The upright arm of the latch-dog strikes agaiustapin, 50, which is supported in a piece attached to the righthand hanger O', thereby retaining thc horizontal part in the proper position to engage the latcb-piece 4T.

As the carriage runs out, thc notched end of the latch-dog 45 passes over and beyond the catchfpiece 47, for a distance equal inanxountto that required to compensate for the shortening oi' the yarn in twisting. so that the notch at the end of the horizontal arm o1' the latch-flog 45, comes in contact with and latches on to the catch-piece 47, simultaneously'with the shipping oi' the belt, which stops thc twisting, and it remains in that position, holdingthe carriage during the hacking oli` ot' the spindles, until the slotted head 33, v

ofthe backing-oit` slide 28, strikes against the upright arm ofthe latch-dog 45, tlierebyfreleasing it from the catch 47, and allowing the carriageto be, run in by thc draught-scroll N and cord 3h.

The lcvcr 35, whichoperates the backing-off clutch, is held in a perpemlicular position by means of a centralizing spring, 51, secured to-anarm, which projects from the right-hand hanger 0'.

lhe spring 51 is provided with an angular notch on its under side, thatlits on to lthe top ot the lever 35, in such amanncr, that when the latter' is pressed ei- 4ther to the right or left by the switch 34, it-raises the spring 51, and when the switch 34 has passed the lcvci' 35, the latter is immediately returned to a central position by the notch in the spring 5l.

larallel to the backing-ott1 slide 2S, and supportel in the same bearing` therewith, is a slide, 52, for disconnecting .the miler-mechanism after the yarn has been wound upon the cops. v

rlhe rear end of the slide 52 strikes against a stoppiecc, 53, which projects forward ti'om the head-trame H, when the carriage isrun in, which throws said slide 52 lbrward, and the ii'tmtcnd thereof' pushes the curved shoulder of the swinging arm 44 oii` from the stud-bolt 40, when 'the fallers are drawn up by the springs rlhe disconnecting-slide 52 is moved back 'by the backing-ott'slidc 2S, which is provided with a piu, 54, that strikes the swing-piece 55, which latter', coming in contact with apiu, 5G, in the side of the disconnecting-slide 52, causes said slide to recede.

An iuclined'lug5, is formed on the slide 52, which bears down the end ot the lever 17, when the slide 52 is moved forward with the carriage, thereby slightly turning the shaft l5, and throwing the winding-clutch V' out ot` action.

The com pensatiug-mechanism, which moves the carriage in to compensate/for the shortening of the yarn mounted on a rocker-frame, 59, that is hinged upon tached to the worm-shaft 12, said shaft being turned,

'as before stated, by the belt R' f1'om the driving-pul ley F.

The rocker-frame is pressed back by a spring, l65, so that the rack 58 is out of gear' while the carriage is being run in. rutas the carriage runsout, a lever, (i6, which projects downward fi'om the carriage-trame 1i, cornes incontaet with the sla-nting point (57, ot the rack 5S, and slides it forward to the extent of t-lre slot bl, when it can go no further.

The end of lever 66, which is bevelled ott at one side, crowds the point 67 to the left, which swings up the rocker 5f), and throws the rack 58 into gear with the pinion 62, whereby the former irnmcdiatel y receives a backward motion, and, by pressing agairrst the end ot' lever' (56, which is caught ou the notch at the righthand side of the point 67, moves the carriage slowly back while the yarn is being twisted.

The lever (i6 is pivoted, near' its upper end, to a supporting-piece, 68, attached to theinside ot' the car'- riage-ti'ame lt, and a set-screw, 69, is arranged through said piece 68, by means of' which the level' 66 may be adjusted to the proper position. i

A spiral wire spring, 7.0, extends from the top end I ot' the lever (56 to the back part of the carriage-frame R, which spring 70 is to prevent breaking the parts in case their' operation is not perfect'.

It will be understood that the power et' the spring 70 is suticient to overcome the. resistance ot' the carriage, so that the latter' will be moved by the pressure ot' the rack 58 against the lever o't. l

larallel to the regulating-spring 21,`and secured to the ti'ont end ofthe shaft 15, in a similar manner, is a spring, 71, having through its end, a bolt, 74, that extends downward ii'om the frame 1t ot the carriage.

The bolt 74 is provided with a nut at its lower end, beneath the spring 71, and by screwing said nut up or down, the'au'rount et' i'riction on the clutch Y' is increased or diminished, as the ease may be.

lhe operation is as follows: Cornmcneing when the carriage starts to run ont'.

The draught-scroll M moves out the carriage, as before stated.

'When sntlicient roving has runfrom the rolls, which are arranged on the top ot' frame A, in the usual manner, to form a str'etch, the speed at which the carriage moves is accelerated, for the purpose ot'strctching the roving, as required.

This accelerating motion is obtained by the regulating-devices and corre-pulleys l and J, in the manner heretofore described.

The carriage runs ont until the stud r' strikes the linger M' on the-rod L', which, acting on the lever K',

i pushes back the ratchet-bar D', andthe latter engages with'the pawl-rod l", whereby the perpendicular slide C" is moved down the distance et' one ratchet, where it is held by the spring nr', which falls into the lower notch a.

l lhe bar Q, being moved by the inclined flange 5, throws ont the clutch O of the draught-scroll M, and stops all further outward motion of the carriage.

lhefleverl 37, striking against the guard 38, throws forward the backing-ott' slide 28, and the shoulder ot' the swinging arm 44 locks on to the studbolt 40,.at

the upper end of the shackle-bar 39. The carriage is gradually run in for a shor't distance, while the yz. 'n is being twisted, by the. compensatirig-mechanism, as and for the purpose stated.

XVhen the yarn is twisted s'niiciently, notice is given by the twist-wheel d, which, being properly adjusted, sets into operation the mechanism that slides the shipper-bar J', and the main belt is thereby shifted from the ratchet-.pulleyE to the tight pulley C, andthe motion of thc ratchet-pulley E and driving-pnlleyF is stopped by suitable mechanism, arranged for that pur'- pose, not shown in the drawings. The end ofthe rod l' is' at the same time brought in contact with the bevelled edge ofthe ratchet-bar D', thereby throwing the latter into action, and the slide C is moved downward by the pawl-rod F' to the second notch ot' the ratchet, which allows a moment of time wherein the motion of the spindles cinay wholly cease; and at the next revelution of the shaft f, the slide C is moved down to the third and last notch of the ratchet, when, the bar Q, being moved by the tlange operates lever' k, and throws in thc clutch P ol'the draught-scroll N, which commences to wind up the cor'd 30, thereby'drawing back the backing-ott' slide 28, the carriage being meanwhile held in position by the latelr-dog 45 and catchpiece 47.

As the slide 28 moves back, the switch 34 throws into action the backing-ott clutch 32, which latter', being operated bythe cor'd or chain 31, turns back the winding-shaft I", and backs ott" the spindle Then the switch has passed the lever 35 ot" the backing-ott clutch, the clutch is thrown ont bythe centr'alizing spring 5l. '..lhe top end of the shackle-bar 39 being drawn back, it pushes up the swinging arm 44 and perpendicular bar 24, which, in connection with the segment 22, lowers the upper faller g2, whereby the yarn is guided upon the cops.

When the slide 28 is drawn back to nearly its t'nll extent, the slotted head 33 strikes the upright arm of the latch-dog` 45, and releases the latter from the catchpiece 47. The disconnecting-dide'52 is also moved back by the pins 54 and 5li and swing-piece 55, thus' removing the lug 57 otl't'rom the lever 17, which latter is drawn up, and the tiietion ofthe whaling-clutch thrown into action by the springs 2l and 71.

The slide 28, having been drawn back to its full extent, the tbrce. of the draught-scroll N now acts upon the carriage, which is run in thereby, the yarn being at the same .time wound upon 4the cops, by the action ot' the cords S and S), which turn the winding-drum \V', together with the winding-shatt P',cylir1der T', and spindles u, as the carriage runs in. lVhen the carriage has run in, and wound up the yarn upon the cops, the end ot the disconnecting-slide 52 comes in contact' with the stop-piece 53, and disconnects the swing-arm 44 from the stud-bolt40, in the shackle-bar 39, thereby releasing the tallers, which are drawn up by the springs It".

The inclined lug 57 runs over the lever' 17, and throws out the whirling-clutch V', while a suitable a1'- ranged stop-dogtln'ows back the shipper-bar J and shift-s the main belt to the ratchet-pulley E, which puts the'spindles again into action. A

The guard 72 presses ont the eatclbpiece m', and the perpendicular slide C is drawn up by its spring 4,

vthereby releasing the flange 5 ti'orn the bar Q, when the latter', being thrown back by the spring 73, operates the levers h and k, whereby the clutch P of the, draught-scroll N isl thrown out, and the clutch Oct' the draught-scroll M is thrown into actiornwhich again runs out the carriage, and the operation is repeated.
